Features of 1070 Aluminum Foil
- High Purity & Excellent Conductivity
With minimal impurities, 1070 foil exhibits outstanding electrical and thermal conductivity, making it particularly suitable for electronic and heat transfer applications.
- Superior Heat Resistance
The material can withstand temperatures up to 420°C, maintaining structural integrity and performance stability even in high-temperature environments.
- Good Mechanical Strength
Featuring a tensile strength of approximately 280 N/cm, the foil provides sufficient durability and resistance to tearing during processing and application.
- Excellent Corrosion Resistance
A protective layer of aluminum oxide (Al₂O₃) naturally forms on the surface, ensuring its strong resistance to moisture, oxidation, and various chemical environments.
- Outstanding Formability & Flexibility
1070 foil offers excellent ductility and elongation, allowing it to be easily processed into complex shapes, ultra-thin gauges, and customized configurations.
